Abstract:
Alternaria lini casing Alternaria blight is probably the main disease problem facing the linseed grower. Alternaria blight can cause severe damage to seedlings, seedlings may be seriously weakened or killed which may result in substantial reduction in plant stand. A total eight fungicides at their recommended dosages were evaluated in vitro by poisoned food technique, against Alternaria lini causing Alternaria blight of linseed. The systemic fungicides viz., Carbendazim 50% WP, Thiophanate methyl 70% WP, Tebuconazole 25% WG, contact fungicides viz., Captan 75% WP, Mancozeb 75% WP and combi fungicides viz., Carboxin 37.5% + Thiram 37.5% 75 WP, Carbendazim 12% + Mancozeb 63% WP were evaluated. However, the fungicide viz., Carboxin 37.5% + Thiram 37.5% 75WP was found most effective with 92.04 per cent mycelial growth inhibition of Alternaria lini followed by Tebuconazole 25% WG (89.93%), Captan 75% WP (72.37%), Carbendazim 12% + Mancozeb 63% 75WP (60.11%), Mancozeb 75% WP (28.82%), Carbendazim 50% WP (22.15%) and Thiophanate methyl 70% WP (12.26%) were found effective against Alternaria lini.
